Vliv vybraných faktorů na porušenou zónu v okolí podzemních děl v pevných horninách

Abstract

This diploma thesis deals with the analysis of the damaged zone around underground work, which is located in hard rocks, and also describes the factors that influence its formation. Analytical and modeling methods, which are described in this work, were used to determine the damaged zone. The analysis of the dameged zone is carried out analytically and with the help of a computer model in the Plaxis 2D Geotechnical Software program. Based on the observation of the lateral pressure coefficient, the radius of the circular underground work and the mechanical characteristics of the rock environment in which the work is built, the achieved results of individual theories are presented here. These results are then evaluated and compared to each other.
